LIQUID-FUEL 0R OIL BURNER.

Specification of Letters Patent.

Application filed June 9, 1916.

To all whom it may concern.

Be it known that I, JOHN R. GREEN, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented new and useful Improvements in Liquid-Fuel or Oil Burners, of which the following is a speciflea-tion.

The invention relates to burners, and more particularly to the class of liquid fuel or oil burners.

The primary object of the invention is the provision of a burner of this character wherein the proper mixture of liquid fuel with air will be had to assure perfect combustion with a minimum consumption of fuel, and the liquid fuel will be vaporized prior to its combustion.

Another object of the invention is the provision of a burner of this character wherein a preheating coil is arranged above and below the burner proper so that the liquid fuel will be heated by the flame from the. burner proper for vaporizing the oil so as to assure perfect combustion, the burner proper being of novel construction to accommodate the preheating coil and to adapt it to fire boxes in stoves or furnaces of various types.

A still further object of the invention is the provision of a burner of this character wherein the construction thereof permits the distribution of the vaporized liquid fuel throughout the. entire burner proper, thus making the blaze uniform and regular the entire area of the burner proper and the arrangement of the preheating coils at the top and bottom of the burner proper assures the quick and perfect vaporizing of the liquid fuel.

A still further object of the invention is the provision of a burner of this character wherein the same is automatically cleaned for dispersing carbon that might accumulate in the continuous use of heavy liquid fuel and the number of burners proper can be increased or decreased as the occasion may demand.

A still further object of the invention is the provision of a burner of this character wherein the burner proper, the manifold and the preheating coils are readily detachable and likewise the cap of the valve casing can be removed so that any sediment can be taken therefrom and also from the oil, thereby avoiding the choking or the rendition of the burner unfit for use.

Serial No. 102,787.

A still further object of the invention is the provision of a burner of this character which is simple in construction, thoroughly reliable and eiiicient in operation, strong, durable, readily and easily applied within or removed from a fire box of a stove or furnace and inexpensive in manufacture and installation.

Other objects Will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the appended claiin.

In the accompanying drawings:

Figure 1 is a top plan view of a burner constructed in accordance with the inven tion;

Fig. 2 is a side elevation thereof;

Fig. 3 is a vertical longitudinal sectional view through the burner on the line 38 of Fig. 1.

Fig. f is a sectional view on the line it of Fig. 1;

Fig. 5 is a sectional view on the line 5 of F ig. 1.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, the burner structure comprises one or a plurality of burner bodies proper A which, when in series, are arranged in spaced relation to each other and are adapted to be located within the fire box of a stove or furnace irrespective of the height thereof, while 'below said burners proper is an oil pan B, it being understood of course that each body A may be of any desirable shape and is formed at its bottom with lugs 10 which rest upon the pan and in this manner the burners are supported elevated therefrom.

The top of each body A is reticulated or formed with slots 11 so that the vaporized fuel can be ignited-when the burners are to be used. Arranged above and below and in close proximity to the top and bottom of one burner body A are preheating coils 12, the inlet lead 13 thereto being connected to and extending from an oil supply tank or other container, while the outlet lead 14 is tapped into a substantially inverted U shaped manifold 15 which is detachably connected with valve casings 16 mounted in the outer end of air and liquid fuel mixers in the forms of tubes 17, which are integrally formed with the bodies A of the burner proper. The outer ends of the tubes carry air regulating inlet shutters 18 which control the inflow of air to the mixing cham-' here 19 interiorly of the tubes 17 so that the oil vapor and air admitted thereto will become properly mixed for the combustion thereof in the burners proper.

Formed in the under side of the tubes 17 are a plurality of apertures 20 which permit the delivery of oil into the pan B for the initial lighting of the burners.

l/Vorking within the valve casings 16 are needle valves :21 which can be manually operated for controlling the flow of the liquid fuel from the manifold 15 to the burners proper, as will be clearly obvious.

On the top of each burner body A are retaining lugs 22 which are adapted to engage with the uppermost coil 12 and prevent displacement thereof relative to the burner body, while the lugs 10 on the bottom of the burner body proper also serve to retain the lowermost coils against displacement. It will be clearly apparent that any one of the burner bodies A can be interchanged with the other and also by reason of the particular construction and the cletachable connection of the burners in series the number thereof can be increased or decreased as the occasion may demand.

It will be apparent that the oil, after leaving the tank or other container therefor, flows through the preheating coils and thence to the manifold, whereupon the preheated oil vapor is delivered to the mixers for the mixing thereof with the proper proportion of air to assure perfect combustion at the burners proper. It is deemed needless to'delineate more fully on the operation of the burners because the same is obvious and, therefore, a more extended explanation has been eliminated.

Having thus described my invention, I claim:

A burner structure comprising a burner body forming a burner proper, preheating coils arranged at the top and bottom of the body, a manifold, a liquid fuel lead to the uppermost coil, an outlet lead from the lowermost coil to the manifold, connections between the manifold and the burner body, a valve for controlling the communication between the manifold and the burner body, means on the burner body for holding the coils against displacement, means for dethe manifold andthe burner body, a mixer located between the manifold and the burner body and having an adjustable air admitting shutter, means for controlling the supply of liquid fuel from the manifold to the mixer, said mixer being formed with outlet apertures, and an oil pan supporting the burner body and adapted to receive oil through the apertures from the mixer.

In testimony whereof I affix my signature.

JOHN R. GREEN.
